Question
Hello doctor,
I have a daughter born in 2000, with a history of asthma from the age of 6 to 12 years old (treatment at the hospital). Now that the Covid-19 vaccine has been administered twice, the heart rate is above 120 beats / min, the blood pressure is normal. So the doctor asked me what is the reason for the high heart rate during Covid vaccination? Is there any medicine to reduce heart rate? I thank the doctor.

Hello,
With the question “What is the reason for the high heart rate during Covid vaccination? ", the doctor would like to answer as follows:
My son's bronchial asthma is cured, so it is not related to increased heart rate. Her heart rate was high because she was worried when she went to the hospital and waited for the vaccine. Therefore, you should let him rest quietly, close his eyes, avoid exercise, calm down for his heart rate to slow down. If it doesn't help, you should take him to the doctor at the vaccination site.
There are drugs to reduce heart rate but need to be examined before giving medicine and prescribed by a doctor.
If you still have questions about the high heart rate during Covid vaccination, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
Best regards!
